I have brought the same side dish to my brother's Thanksgiving six years running.
The sixth year, I pulled the sheet pan out and the sprouts on it were black.
Not caramelized. Black.
The sweet potato cubes underneath were still pale and slightly raw in the middle.
My wife looked at the tray, then looked at me, and asked whether there was a backup plan.
There was not.
I had done exactly what every recipe I could find told me to do, which was toss everything in the maple dijon and roast it all together.
Well, maple syrup is sugar, and sugar sitting on a thin outer sprout leaf at 425°F goes black long before a sweet potato cube is cooked through.
Nobody says that part out loud.
So now I roast the vegetables plain and whisk the dressing while they're in the oven.
The sprouts come out with a deep brown cut face and their outer leaves still on them.
The sweet potato gets an eight minute head start, so both finish at the same moment.
Everything lands in a bowl warm and gets tossed in a glossy amber-brown maple dijon right then.
Toasted pecans, dried cranberries, and crumbled goat cheese going soft against the hot vegetables.
Year seven went a lot better.
Why You'll Love This Salad
This is a holiday side dish that behaves like a weeknight one. One pan, one bowl, and a dressing you whisk with a fork.
- Served warm. Not a chilled leaf salad. The vegetables come off the pan hot and the goat cheese softens into them.
- One sheet pan. Sweet potato, sprouts, and red onion all roast together on the same tray.
- The dressing goes on last. Which is the whole reason nothing burns and everything tastes like caramelized vegetable instead of scorched sugar.
- Sweet, salty, tangy, and bitter, all present. Maple against dijon, sprouts against cranberries, goat cheese against pecans.
- Holiday ready, Tuesday easy. It sits happily on a Thanksgiving table and it also feeds four people next to a roast chicken in November.
- Mostly make-ahead. The dressing keeps five days and the vegetables can be cut the night before.
The Maple Dijon Mistake Everyone Makes
Do not roast the vegetables in the maple dijon. I know that's what most versions tell you to do. It's the reason your sprouts come out bitter.
Maple syrup is sugar, and sugar has a burn point.
A halved brussels sprout has papery outer leaves that are maybe a millimeter thick.
Coat one in syrup, put it in a 425°F oven, and those leaves are carbon in about ten minutes.
Meanwhile a ¾ inch sweet potato cube needs roughly 33 minutes to go tender and caramelized in the middle.
You cannot have both. Something has to burn.
And burnt maple doesn't taste like caramel. It tastes like acrid, back-of-the-throat bitterness that coats everything else on the tray.
The fix costs you nothing.
Roast the vegetables in plain olive oil, salt, and pepper, where they can go as dark as they like without any sugar involved.
Whisk the maple dijon in a jar while the oven does its work.
Then tip the hot vegetables into a bowl and toss them in the dressing off the heat.
Pro tip: tossing while everything is still hot matters. Warm vegetables drink the dressing in instead of wearing it, and the maple stays sweet because it never met the oven.
Ingredients and Substitutions
Nothing here is hard to find in November. Most of it is already on your shopping list for the holiday anyway.
- Sweet potatoes (1 ½ pounds, peeled). Cut into ¾ inch cubes. Smaller and they collapse into mush before the sprouts are ready. Peel them, because the skin goes leathery at this temperature and it's unpleasant in a forkful.
- Brussels sprouts (1 pound). Fresh, trimmed, and halved through the stem so each half holds together. Frozen sprouts carry too much water and they steam instead of browning. They will never give you that deep brown cut face, no matter how hot the oven is.
- Red onion (1 small). Cut into ½ inch wedges. It goes sweet and floppy in the oven and stops the bowl from being just two vegetables.
- Olive oil (2 tablespoons for roasting, ¼ cup for the dressing). Split it. The roasting oil is doing a job, the dressing oil is doing a different one.
- Pure maple syrup (2 tablespoons). Real maple. Pancake syrup is corn syrup with caramel color and it tastes like it in a vinaigrette.
- Dijon mustard (2 tablespoons). The sharp yellow-grey kind. Not honey mustard, which brings its own sugar and throws the balance off. The dijon is also the emulsifier here, so it earns its place twice.
- Apple cider vinegar (2 tablespoons). The single most common thing missing from other versions of this salad. Without acid the dressing reads flat and cloying.
- Garlic powder (¼ teaspoon). Powder, not fresh. Raw minced garlic in a cold dressing bites, and cooked garlic isn't an option here.
- Pecan halves (½ cup). Toasted in a dry pan for 4 minutes before they go anywhere near the bowl. Untoasted pecans taste like nothing.
- Dried cranberries (⅓ cup). Chewy, tart, and they're the color that makes this bowl look like a holiday.
- Goat cheese (2 ounces, crumbled). Tangy and it goes creamy against the hot vegetables. Feta works, blue cheese works if your table likes blue cheese.
- Kosher salt and black pepper. Salt the vegetables before roasting, not after. Salt on the raw surface pulls moisture out and helps them brown.
How to Roast Them So They Finish Together
The whole recipe is a timing problem. Two vegetables, two different clocks, one pan.
Step 1: Heat the oven properly
Get it to 425°F and let it sit there for a full ten minutes after the light goes off.
A pan going into an oven that's still climbing gives you steamed vegetables.
Step 2: Sweet potatoes first
Toss the cubes with 1 tablespoon of the olive oil, ½ teaspoon salt, and the pepper.
Spread them on a rimmed sheet pan in a single layer with space between them.
Roast 8 minutes before anything else joins them.
Step 3: Sprouts and onion, cut side down
Toss the halved sprouts and the onion wedges with the remaining 1 tablespoon of oil and ¼ teaspoon salt.
Pull the pan out, push the potatoes to one side, and lay every sprout cut face down against the hot metal.
That contact is the difference between a browned sprout and a beige one. It's one sentence of instruction and it changes how the whole bowl looks.
Back in the oven for 25 minutes.
Step 4: Know what done looks like
The sweet potato cubes should have dark caramelized corners and give easily to a knife tip while still holding their square shape.
The sprout cut faces should be a deep even brown, almost mahogany, with the outer leaves crisp and golden rather than black.
Total oven time is 33 minutes. Give or take, depending on your oven.
The Dressing
Order matters more than technique here. Put the oil in last and you get an emulsion. Put it in first and you get a slick.
Whisk the dijon, cider vinegar, maple syrup, garlic powder, and salt together first, until it looks like a smooth brown paste.
Then add the olive oil in a thin stream while you keep whisking.
The mustard does the emulsifying, which is why it has to be fully mixed with the vinegar before any oil shows up.
Done right, the dressing is glossy, opaque, and amber-brown, thick enough to coat a sweet potato cube and stay there.
Done wrong, it separates into a pale layer sitting on a pool of oil at the bottom of the jar.
Sound fussy? It takes ninety seconds in a jam jar with a fork.
Toppings and Variations
The vegetables and the dressing are the recipe. Everything else on this list is negotiable.
- Swap the goat cheese. Feta is saltier and holds its shape. Blue cheese is a bigger swing and works beautifully against maple.
- Swap the nuts. Walnuts, pumpkin seeds, or sliced almonds. Toast whichever you use.
- Pomegranate seeds instead of cranberries. Less sweet, more pop, and they look fantastic.
- Add bacon. Four slices, cooked crisp and crumbled in at the end. It turns this into a completely different and very popular side dish.
- Make it a main. A drained can of chickpeas, tossed on the pan with the sprouts, roasts up crisp and turns this into lunch.
- Fresh thyme. A few leaves over the top at the end if you want it to look like more effort than it was.
Make It Ahead for a Holiday Table
Some of this can happen the day before, and some of it absolutely cannot. Knowing which is which is what keeps your oven free on Thanksgiving morning.
- The dressing. Make it up to 5 days ahead and keep it in a sealed jar in the fridge. The oil will firm up. Let it sit out for twenty minutes and shake it.
- The vegetables, cut. Cube the sweet potatoes and halve the sprouts the night before. Store them in separate bags in the fridge, sprouts loosely so they don't sweat.
- The pecans. Toast them days ahead. They keep fine in a jar at room temperature.
- The roasting. Same day, no exceptions. Roasted and reheated sprouts go soft and lose the crisp edge that makes them worth eating.
- Leftovers. Three days in the fridge. They're good cold straight from the container, and honestly that's how most of mine get eaten.
Fair warning: if you need to hold the finished salad for an hour, hold the goat cheese back and crumble it on right before it hits the table.
What to Serve It With
This was built for a roast. It's rich enough to stand next to one and acidic enough to cut through it.
Roast turkey is the obvious home for it, and it's what I make it for most years.
It's just as good next to a pork loin, a roast chicken on a Sunday, or a holiday ham.
For a vegetarian table, put it next to a big pot of wild rice and call it dinner.
Who doesn't love a side dish that quietly outshines the main?
Recipe
Roasted Sweet Potato and Brussels Sprout Salad with Maple Dijon
Ingredients
For the Salad
- 1 ½ pounds sweet potatoes peeled and cut into ¾ inch cubes
- 1 pound brussels sprouts trimmed and halved through the stem
- 1 small red onion cut into ½ inch wedges
- 2 tablespoons olive oil divided
- ¾ teaspoon kosher salt divided
- ¼ teaspoon black pepper
- ½ cup pecan halves roughly chopped and toasted
- ⅓ cup dried cranberries
- 2 ounces goat cheese crumbled
Maple Dijon Dressing
- 2 tablespoons Dijon mustard
- 2 tablespoons pure maple syrup
- 2 tablespoons apple cider vinegar
- ¼ cup extra virgin olive oil
- ¼ teaspoon garlic powder
- ¼ teaspoon kosher salt
- ⅛ teaspoon black pepper or to taste
Instructions
Roast the Vegetables
- Heat the oven to 425F and let it hold that temperature for a full 10 minutes before the pan goes in.
- Toss the sweet potato cubes with 1 tablespoon of the olive oil, ½ teaspoon of the salt, and the pepper. Spread them on a rimmed sheet pan in a single layer with space between them and roast 8 minutes.
- Toss the halved sprouts and onion wedges with the remaining 1 tablespoon oil and ¼ teaspoon salt. Pull the pan out, push the potatoes to one side, and lay every sprout cut face down against the hot metal.
- Return the pan to the oven and roast 25 minutes more, until the sweet potato corners are dark and a knife tip slides in easily, and the sprout cut faces are deep brown.
Make the Dressing
- While the vegetables roast, whisk the Dijon, cider vinegar, maple syrup, garlic powder, salt, and pepper together until smooth.
- Add the olive oil in a thin stream, whisking constantly, until the dressing is glossy, opaque, and amber brown. It should coat the back of a spoon.
Assemble
- Tip the hot vegetables into a large bowl and pour over about three quarters of the dressing. Toss gently so the sprout halves stay intact.
- Add the toasted pecans and dried cranberries and toss once more. Taste and add the remaining dressing if you want it.
- Scatter the crumbled goat cheese over the warm salad and serve straight away.
Notes
- Never roast in the dressing: maple syrup is sugar and it burns black on thin sprout leaves long before the sweet potato is cooked.
- Cut side down: laying each sprout half against the hot pan is what gives you a deep brown face instead of a beige one.
- Make ahead: the dressing keeps 5 days refrigerated and the vegetables can be cut the night before. Roast the same day.
- Holding it: keep the goat cheese back and crumble it on right before serving.
- Leftovers: 3 days in the fridge, good cold.
